. Application ma December f This invention relates to oil burners andmore articularly to that type of oil burner used or heating dwellings,and the like.-

Oil burners now in use for the heating of houses, etc.` are generally ofthe automatic type and require a number of accessories such asthermostats, electric motors, blowers, etc. with the resultthat the costof installing an automatic oil burner is prohibitive to persons ofmoderate means;

It is an object of my invention to provide dwellings not exceeding eightrooms, and which maybe cheaply made so that the total cost of installinga complete oil burner will,

be within the means of all. Also my burner is so constructed ,that thefuel consumption ryillbie moderate, and the cost of upkeep -negigi e.

A further object is to provide a burner having a surface/over which oil`fed by gravity may flow, the surface being so shaped as to prevent theoil from collecting in spots, and

the accumulating of carbon deposits on the birner due to incompletecombustion of the o1 A furtherobject is to rovide means forsuper-heating air' supplie to the burner so that the oil will be heatedto a gaseous state These and other objects are attained by thenovelconstiuction combination and arrangement of parts hereinafterdescribed and shown in the accompanying drawing, constituting a materialpart of this disclosure, and

mwhich:

Figure 1 is an elevational view of an'oil burning system. Figure 2 isacross-sectiona1 side view of the improved burner.

Fi ure 3 is a plan view of the air heating cham er used with the burner.Figure 4 is a plan view of the burner. Referring to the drawings, inburner is shown consisting of a bowl shape member 3, having a pluralityof radial extensions 4, which are provided with flanges 5 to enable theburner to be mounted by suitable means on the grate 2, of a furnace.

In the center of the member 3 is an integral upstanding hollow conicalprojection 6, which terminates in a spherical cap thelatter beingapertured at 9 to accommodate the p ipe 10, through which oil may be fedby gravity. 'A plurality of apertures 8 are ture 17 accommodates aprovided in 17, 1987. Serial N0. 240,690.

3 to enable the pasgases therethrough, member 3, an a erd'rain pipe 18,w ich `leads to an automatic cut-off device 19, the latter being ofstandard design. Should for any reason, the flame be extinguished, theo'il will, of course, continue to flow through pipe 10, over thespherical cap 7 and fall into the bottom of member 3, from whence itwill be the sides the member sage of air and burned In vthe bottom ofthe drained oil throu h pipe 18 until it reaches the automatic. cut-o19, which will then actuate pipe 10.

It will be noted that the extensions 4 are provided with .apertures 20and upstanding flanges 15 which facilitate the mounting of the airchamber 11, the latter having a plurality of hollow legs 12 adapted tofit over the apertures are very thin andare corru at 13, so that thepassage o air therethroughl will be retarded, resulting in thesuper-heating of the air to such an extent that when such air passesthrough the opening 14 in the chamber 11, it will have attained atemperature sufficient to volatilize the oil which iiows over thesurface of ca 7. Such action, obv viously, results in the Burning of theoil in a gaseous state, and consequently, complete combustion withpractically 'no carbon deposits. Y l The spherical shape of the cap 7the surfacebf which is highly polished, prohibitsV the collecting ofcarbon deposits thereon, and

20. The walls, of the legs 12 ated or waved as a valve to stop thefurther flow of oil through also causes the oil exuding from pipe 10 toby the pipe 16, or the oil may be ignited by other means such as theburning of ,paper in suiiicient to heat the cap 7 considerably and -toignite and cause the exuding oil to burn as it passes in a. film overthe spherical cap 7. While these initial operations are going on, theair in the legs 12 of chamber 11 is being heated to a high temperature,and within a few seconds the superheated air passing through the opening14 will volatilize the oil exuding from pipe 10 resulting in thecomplete combustion of the oil and a tremendous eat for the pur oseintended.

Normally, suc a burner, designed to heat the member3. This initialburning of oil is a dwelling not exceedin rooms, will not.

consume over one half ga l n of oil perhour,

Yand on mild days the flow of oil through pipe 10 may be controlled b -avalve so that a smaller quantity of oi will 'be consumed each hour.

From ,the above description it will-be seen that Ihave rovided aneicient oil burning apparatus w ich may be manufactured an installed at'low cost, and yet satisfactorily heat dwellings with a minimumexpenditure for fuels. v

The foregoing disclosure is to be regarded as descriptive andillustrative only, and not' as restrictive or limitative of theinvention,

-of which obviously an embodiment may be constructed including manymodifications without departing from the general scope 'herein indicatedand denoted by the appends said cap having an aperture therethrough totherethrough.

. A. .1,oes,`aes

accommodate a pipepu standin` standing ilanges, said extensions' havingapertures coincidin with the hollow legs; the walls of said ho low lebeing4 very thin and corrugated to retard t e passage of air 2. In anoil burning apparatus, a member having extensions by which it may bemounted on a grate,a frusto-conical rejection in the center of saidmember, a polished spherical cap "removably mounted on the projection,said cap `havin an aperture therethrough to accommo ate a pi e, a hollowchamber having a plurality o hollow legs adapted to be mounted on saidmember tocoincide with apertures therein, the walls of said leffs beingcorrugated to retard the passage otP air therethrough.

3. In an oil burning apparatus, a member adapted to be mounted on agrate, a frustoconical projection in the center of said member, a highlypolished spherical cap remov-A ably mounted on the projection, and meansmounted on said member for superheating air. j Y
